背景技术Background technique
空调器是能够为室内制冷/制热的设备，现有空调器的控制逻辑大致为：在制冷工况下，室内风机转动、压缩机转动并且电子膨胀阀打开，在室内温度达到目标温度后空调器停止制冷，此时室内风机继续转动、压缩机停转并且电子膨胀阀关闭，然后室内温度会升高，在室内温度升高一定程度后，空调器会重新开始制冷，此时压缩机再次开始转动并且电子膨胀阀打开；在制热工况下，室内风机转动、压缩机转动并且电子膨胀阀打开，在室内温度达到目标温度后空调器停止制热，此时室内风机继续转动、压缩机停转并且电子膨胀阀关闭，然后室内温度会降低，在室内温度降低一定程度后，空调器会重新开始制热，此时压缩机再次开始转动并且电子膨胀阀打开。由此可知，现有空调器无论在制冷还是制热时，都会频繁地开启和关闭压缩机，导致室内环境温度的波动会比较大，降低用户舒适度，且会降低压缩机的使用寿命。The air conditioner is a device capable of cooling / heating indoors. The control logic of the existing air conditioner is roughly: Under cooling conditions, the indoor fan rotates, the compressor rotates and the electronic expansion valve opens, and the air conditioner is operated after the indoor temperature reaches the target temperature. The air conditioner stops cooling. At this time, the indoor fan continues to rotate, the compressor stops and the electronic expansion valve is closed, and then the indoor temperature will rise. After the indoor temperature has risen to a certain extent, the air conditioner will resume cooling and the compressor will start again. Rotate and the electronic expansion valve opens; Under heating conditions, the indoor fan rotates, the compressor rotates, and the electronic expansion valve opens. When the indoor temperature reaches the target temperature, the air conditioner stops heating. At this time, the indoor fan continues to rotate and the compressor stops. Turn and the electronic expansion valve is closed, and then the indoor temperature will decrease. After the indoor temperature is reduced to a certain extent, the air conditioner will resume heating, at this time the compressor will start to rotate again and the electronic expansion valve will open. It can be known that the existing air conditioner frequently turns on and off the compressor when it is cooling or heating, resulting in relatively large fluctuations in indoor ambient temperature, reducing user comfort, and reducing the service life of the compressor.
因此，本领域需要一种新的用于空调器的控制方法及相应的空调器来解决上述问题。Therefore, there is a need in the art for a new control method for an air conditioner and a corresponding air conditioner to solve the above problems.

在另一方面，本发明还提供了一种空调器，该空调器包括控制器，该控制器配置成能够执行上述的控制方法。In another aspect, the present invention also provides an air conditioner including a controller configured to be capable of performing the above-mentioned control method.
本领域技术人员能够理解的是，在本发明的优选技术方案中，先获取室内环境温度和空调器的当前运行模式，然后根据室内环境温度和空调器的当前运行模式，判断是否切换空调器的运行模式以及调整压缩机的频率、电子膨胀阀的开度和室内机的风机转速，通过这样的设置，可以使空调器在不同的模式之间灵活切换，并且模式切换的同时或者之后可以对压缩机的频率，电子膨胀阀的开度和室内机的风机转速进行组合控制，使得空调器能够在最合适的工况下进行制冷/制热。具体而言，如果空调器的当前运行模式为制冷模式，当室内环境温度达到目标温度(如用户设定的需求温度)后则停止正常的制冷，进入微风模式，即室内风机的转速降低并保持低转速(档位)运转，并且压缩机降频运行但不停机，同时减小电子膨胀阀的开度，使得室内环境温度不会急剧升高，而是缓缓升高，提高用户舒适度，而在室内环境温度升高一定程度后，空调器由微风模式切换为正常的制冷模式，此时只需将压缩机升频运行，提高室内风机的转速并增大电子膨胀阀的开度即可；如果空调器的当前运行模式为制热模式，当室内环境温度达到目标温度(如用户设定的需求温度)后则停止正常的制热，进入微风模式，即室内风机的 转速降低并保持低转速(档位)运转，并且压缩机降频运行但不停机，同时减小电子膨胀阀的开度，使得室内环境温度不会急剧下降，而是缓缓下降，提高用户舒适度，而在室内环境温度下降一定程度后，空调器由微风模式切换为正常的制热模式，此时只需将压缩机升频运行，提高室内风机的转速并增大电子膨胀阀的开度即可。由此可见，与现有技术相比而言，本发明在空调器制冷/制热过程中，如果室内环境温度达到目标温度后，空调器会直接进入微风模式，使得室内的环境温度不会急剧变化，从而尽可能长时间地使室内环境温度保持在目标温度附近，避免室内环境温度发生较大波动，进而提升用户舒适度，且压缩机在进行模式切换过程中仅是进行降频和升频操作，并未停机，避免压缩机频繁开闭，从而提高压缩机的使用寿命。Those skilled in the art can understand that in the preferred technical solution of the present invention, first obtain the indoor ambient temperature and the current operating mode of the air conditioner, and then determine whether to switch the air conditioner according to the indoor ambient temperature and the current operating mode of the air conditioner. The operating mode and adjusting the frequency of the compressor, the opening of the electronic expansion valve, and the fan speed of the indoor unit. Through this setting, the air conditioner can be flexibly switched between different modes, and the compression can be performed at the same time or after the mode is switched. The frequency of the unit, the opening degree of the electronic expansion valve and the fan speed of the indoor unit are combined to control, so that the air conditioner can perform cooling / heating under the most suitable working conditions. Specifically, if the current operating mode of the air conditioner is the cooling mode, when the indoor ambient temperature reaches the target temperature (such as the user-set demand temperature), the normal cooling is stopped and the breeze mode is entered, that is, the speed of the indoor fan is reduced and maintained. Low speed (gear) operation, and the compressor runs at a reduced frequency without stopping, and at the same time reduces the opening of the electronic expansion valve, so that the indoor ambient temperature does not rise sharply, but slowly rises to improve user comfort. After the indoor ambient temperature rises to a certain degree, the air conditioner switches from the breeze mode to the normal cooling mode. At this time, it is only necessary to increase the frequency of the compressor to increase the speed of the indoor fan and increase the opening of the electronic expansion valve. ; If the current operation mode of the air conditioner is heating mode, when the indoor ambient temperature reaches the target temperature (such as the user-set demand temperature), the normal heating is stopped and the breeze mode is entered, that is, the speed of the indoor fan is reduced and kept low. Speed (gear) operation, and the compressor runs at a reduced frequency without stopping, and at the same time reduces the opening of the electronic expansion valve, so that the indoor ambient temperature will not be sharp However, after the indoor environment temperature drops to a certain extent, the air conditioner switches from the breeze mode to the normal heating mode. At this time, the compressor only needs to run at a higher frequency to improve the indoor fan. Speed and increase the opening of the electronic expansion valve. It can be seen that compared with the prior art, during the cooling / heating process of the air conditioner of the present invention, if the indoor ambient temperature reaches the target temperature, the air conditioner will directly enter the breeze mode, so that the indoor ambient temperature will not be sharp. Change, so as to keep the indoor environment temperature near the target temperature for as long as possible to avoid large fluctuations in the indoor environment temperature, thereby improving user comfort, and the compressor only performs frequency reduction and frequency up during the mode switching process The operation has not been stopped to avoid frequent opening and closing of the compressor, thereby increasing the service life of the compressor.
进一步地，在导风板上不具有出风孔且空调器由制冷模式切换至微风模式时，将导风板调整至最高的位置可以避免空调器吹出的制冷气体向下直吹，从而避免制冷气体使人体感觉不适，进一步提升用户舒适度。Further, when the air deflector does not have air outlet holes and the air conditioner is switched from the cooling mode to the breeze mode, adjusting the air deflector to the highest position can prevent the refrigerating gas blown out by the air conditioner from blowing downward, thereby avoiding refrigeration The gas makes the human body feel uncomfortable and further enhances user comfort.
更进一步地，在导风板不具有出风孔且空调器由制热模式切换至微风模式时，将导风板调整至最低的位置可以避免空调器吹出的制热气体在室内的上方堆积而迟迟不向室内下方移动，从而避免制热气体无法及时触及人体而使用户感受不到空调器制热，更进一步提升用户舒适度。Furthermore, when the air deflector has no air outlet and the air conditioner is switched from the heating mode to the breeze mode, adjusting the air deflector to the lowest position can prevent the heating gas blown out by the air conditioner from accumulating above the room and Do not move to the lower part of the room slowly, so as to avoid that the heating gas cannot touch the human body in time and make the user not feel the heating of the air conditioner, and further improve the comfort of the user.
再进一步地，在导风板上具有出风孔且空调器由制冷/制热模式切换至微风模式时，可以将导风板完全关闭并通过导风板上的出风孔向室内送风，从而保证空调器能够持续吹出微风，使室内环境温度不会发生急剧变化，提升用户体验。Furthermore, when the air deflector has air outlets and the air conditioner is switched from the cooling / heating mode to the breeze mode, the air deflector can be completely closed and air can be sent to the room through the air outlets on the air deflector. This ensures that the air conditioner can continue to blow the breeze, so that the indoor ambient temperature does not change sharply, and the user experience is improved.
此外，本发明在上述技术方案的基础上进一步提供的空调器由于采用了上述的控制方法，进而具备了上述控制方法所具备的技术效果，并且相比于改进前的空调器，本发明的空调器在对室内进行制冷/制热时不会频繁地开闭压缩机，使室内环境温度不会出现较大波动，提高用户舒适体验度，并且提高压缩机的使用寿命。In addition, the air conditioner further provided by the present invention on the basis of the above technical solution adopts the above control method, and further has the technical effects of the above control method. Compared with the air conditioner before the improvement, the air conditioner of the present invention The compressor does not frequently open and close the compressor when cooling / heating the room, so that the indoor ambient temperature does not fluctuate greatly, improving the user's comfort experience, and increasing the service life of the compressor.

Among them, adjusting the frequency of the compressor, the opening degree of the electronic expansion valve, and the fan speed of the indoor unit can be performed while switching the operation mode of the air conditioner, or after switching the operation mode of the air conditioner, that is, when the air conditioner receives the switch Adjust the frequency of the compressor, the opening degree of the electronic expansion valve, and the fan speed of the indoor unit at the same time or after the command. In addition, adjusting the frequency of the compressor, adjusting the opening degree of the electronic expansion valve, and adjusting the fan speed of the indoor unit can be performed synchronously or asynchronously. Those skilled in the art can flexibly set and adjust the frequency of the compressor in practical applications.

However, such changes in adjusting the frequency of the compressor, adjusting the opening degree of the electronic expansion valve, and adjusting the rotation speed of the fan of the indoor unit should not limit the present invention.
优选地，“根据室内环境温度和空调器的当前运行模式，选择性地切换空调器的运行模式并调整压缩机的频率、电子膨胀阀的开度以及室内机的风机转速”的步骤包括：如果空调器的当前运行模式为制冷模式并且室内环境温度达到第一预设温度，则将空调器的运行模式切换为微风模式并降低压缩机频率，减小电子膨胀阀的开度以及降低室内机的风机转速；如果空调器的当前运行模式为制冷模式并且室内环境温度未达到第一预设温度，则空调器不切换运行模式并且不调整压缩机的频率、电子膨胀阀的开度以及室内机的风机转速。其中，第一预设温度可以为用户设定的目标温度，即只有当室内环境温度达到用户设定的需求温度时空调器才会由正常的制冷模式切换为微风模式并降低压缩机频率，减小电子膨胀阀的开度以及降低室内机的风机转速。当然，第一预设温度还可以为本领域技术人员根据试验为空调器预先设定的温度值，或者本领域技术人员根据经验为空调器预先设定的温度值。这种第一预设温度具体温度值的选取和设定方式并不能构成对本发明的限制。进一步优选地，“根据室内环境温度和空调器的当前运行模式，选择性地切换空调器的运行模式并调整压缩机的频率、电子膨胀阀的开度以及室内机的风机转速”的步骤还包括：如果空调器的当前运行模式为微风模式并且室内环境温度达到第二预设温度，则将空调器的运行模式切换为制冷模式并提高压缩机的频率、增大电子膨胀阀的开度以及提高室内机的风机转速；如果空调器的当前运行模式为微风模式并且室内环境温度未达到第二预设温度，则将空调器的运行模式不切换为制冷模式并且不调整压缩机的频率、电子膨胀阀的开度以及室内机的风机转速，其中，第二预设温度大于第一预设温度。即在空调器由正常的制冷模式切换为微风模式后，但是空调器此时并不是完全不制冷，而是进行微制冷，相较于现有技术中直接将压缩机完全停转的技术方案，采用本发明的技术方案可以使室内环境温度以非常缓慢的速度升高，在室内环境温度升高至第二预设温度时，空调器需要重新由微风模式切换至制冷模式，进行正常的制冷。在上述技术方案中，第二预设温度可以设定为相比于第一预设温度大1摄氏度，或者2摄氏度等，本领域技术人员可以在实际应用 中根据多次试验、自身经验、气候或者地域等多方面因素灵活地设定第二预设温度的具体温度值，只要通过第二预设温度确定的温度分界点能够使空调器由微风模式切换为制冷模式即可。Preferably, the step of "selectively switching the operation mode of the air conditioner and adjusting the frequency of the compressor, the opening degree of the electronic expansion valve and the fan speed of the indoor unit according to the indoor ambient temperature and the current operation mode of the air conditioner" includes: if The current operating mode of the air conditioner is the cooling mode and the indoor ambient temperature reaches the first preset temperature, then the operating mode of the air conditioner is switched to the breeze mode and the frequency of the compressor is reduced, the opening degree of the electronic expansion valve is reduced, and the indoor unit's Fan speed; if the current operating mode of the air conditioner is cooling mode and the indoor ambient temperature does not reach the first preset temperature, the air conditioner does not switch the operating mode and does not adjust the frequency of the compressor, the opening degree of the electronic expansion valve, and the indoor unit ’s Fan speed. The first preset temperature may be a target temperature set by the user, that is, the air conditioner will switch from the normal cooling mode to the breeze mode and reduce the frequency of the compressor only when the indoor ambient temperature reaches the user-set demand temperature. The opening of the small electronic expansion valve and reducing the fan speed of the indoor unit. Of course, the first preset temperature may also be a temperature value preset for the air conditioner by a person skilled in the art according to tests, or a temperature value preset for the air conditioner by a person skilled in the art based on experience. The selection and setting of the specific temperature value of the first preset temperature cannot constitute a limitation on the present invention. Further preferably, the step of “selectively switching the operation mode of the air conditioner and adjusting the frequency of the compressor, the opening degree of the electronic expansion valve, and the fan speed of the indoor unit according to the indoor ambient temperature and the current operation mode of the air conditioner” further includes: : If the current operating mode of the air conditioner is the breeze mode and the indoor ambient temperature reaches the second preset temperature, switch the operating mode of the air conditioner to the cooling mode and increase the frequency of the compressor, increase the opening of the electronic expansion valve, and increase Fan speed of the indoor unit; if the current operating mode of the air conditioner is the breeze mode and the indoor ambient temperature does not reach the second preset temperature, the operating mode of the air conditioner is not switched to the cooling mode and the frequency and electronic expansion of the compressor are not adjusted The opening degree of the valve and the fan speed of the indoor unit, wherein the second preset temperature is greater than the first preset temperature. That is, after the air conditioner is switched from the normal cooling mode to the breeze mode, but the air conditioner is not completely refrigerated at this time, but is micro-refrigerated. Compared with the technical solution of directly stopping the compressor completely in the prior art, By adopting the technical solution of the present invention, the indoor ambient temperature can be raised at a very slow rate. When the indoor ambient temperature rises to a second preset temperature, the air conditioner needs to switch from the breeze mode to the cooling mode again for normal cooling. In the above technical solution, the second preset temperature may be set to be 1 degree Celsius or 2 degrees Celsius higher than the first preset temperature, etc. A person skilled in the art may apply multiple tests, own experience, and climate in actual applications. The specific temperature value of the second preset temperature can be flexibly set by various factors such as regions or regions, as long as the temperature cutoff point determined by the second preset temperature can switch the air conditioner from the breeze mode to the cooling mode.

This control method is suitable for the structure without air outlets on the air guide plate of the indoor unit of the air conditioner. Since the air blown from the indoor unit of the air conditioner is cold air after the cooling mode is switched to the light air mode, this cold air ratio is The proportion of indoor air is large, and it will sink in the indoor air. If the position of the air deflector is set low, the wind blown by the indoor unit will be directly blown to the human body, which will make the human body feel uncomfortable and even cause illness. Under this working condition, setting the position of the air guide plate of the indoor unit at the highest position can make the cold air blow toward the uppermost part of the room as much as possible, and then make the cold air sink in the room uniformly and slowly.

Of course, the third preset temperature may also be a temperature value preset for the air conditioner by a person skilled in the art based on tests, or a temperature value preset for the air conditioner by a person skilled in the art based on experience. The manner of selecting and setting the specific temperature value of the third preset temperature cannot constitute a limitation on the present invention. Further preferably, the step of “selectively switching the operation mode of the air conditioner and adjusting the frequency of the compressor, the opening degree of the electronic expansion valve, and the fan speed of the indoor unit according to the indoor ambient temperature and the current operation mode of the air conditioner” further includes: : If the current operating mode of the air conditioner is the breeze mode and the indoor ambient temperature reaches the fourth preset temperature, switch the operating mode of the air conditioner to the heating mode and increase the frequency of the compressor, increase the opening of the electronic expansion valve, and Increase the fan speed of the indoor unit; if the current operating mode of the air conditioner is the breeze mode and the indoor ambient temperature does not reach the fourth preset temperature, the operating mode of the air conditioner is not switched to the heating mode and the frequency of the compressor is not adjusted, Among the opening degree of the electronic expansion valve and the fan speed of the indoor unit, the fourth preset temperature is lower than the third preset temperature. That is, after the air conditioner is switched from the normal heating mode to the breeze mode, the air conditioner does not completely stop heating at this time, but performs micro heating. Compared with the prior art, the compressor is completely stopped. Technical solution. The technical solution of the present invention can reduce the indoor ambient temperature at a very slow rate. When the indoor ambient temperature decreases to the fourth preset temperature, the air conditioner needs to switch from the breeze mode to the heating mode again for normal operation. Heating. In the above technical solution, the fourth preset temperature may be set to be 1 degree Celsius or 2 degrees Celsius lower than the third preset temperature, etc. A person skilled in the art may apply multiple tests, own experience, and climate in actual applications. The specific temperature value of the fourth preset temperature can be flexibly set by various factors such as regions or regions, as long as the temperature cutoff point determined by the fourth preset temperature can enable the air conditioner to switch from the breeze mode to the heating mode.
进一步优选地，在“降低压缩机频率，减小电子膨胀阀的开度以及降低室内机的风机转速”的步骤的同时，控制方法还包括：将室内机的导风板调整至第二极限位置，其中，第二极限位置为导风板的最低位置。这种控制方式适用于空调器的室内机导风板上不具有微出风孔的结构，由于在制热模式切换至微风模式后，空调器室内机吹出的风为热空气，这种热空气比室内空气的比重小，会在室内空气中上浮，如果导风板位置设置得较高易造成室内机吹出的风全部浮于室内的上方，从而使人体无法感受到空调器微制热，因此，在此工况下，本发明将室内机导风板的位置设置在最低位置可以使热空气尽可能地向室内的最下方吹，然后使热空气在室内均匀且缓慢地上浮，从而使室内的空气均匀制热，提高用户的舒适度。Further preferably, while the steps of "reducing the frequency of the compressor, reducing the opening degree of the electronic expansion valve, and reducing the fan speed of the indoor unit", the control method further includes: adjusting the air deflector of the indoor unit to the second limit position Among them, the second extreme position is the lowest position of the wind deflector. This control method is suitable for the structure without air outlets on the air guide plate of the indoor unit of the air conditioner.

At the same time as the steps of “reducing the frequency of the compressor, reducing the opening degree of the electronic expansion valve, and reducing the fan speed of the indoor unit”, the control method further includes: Including: adjusting the air deflector of the indoor unit to the closed position. Corresponding to the above embodiment, if a plurality of air outlet holes (preferably micro holes) have been provided on the air deflector itself, the air deflector of the indoor unit can be directly closed to achieve micro heating in the room.
需要说明的是，在上述技术方案中，第一预设温度和第三预设温度可以设定为相等的温度值，也可以设定为不相等的温度值，本领域技术人员可以在实际应用中灵活地设置第一预设温度和第三预设温度的相对关系。此外，在由制冷/制热模式切换为微风模式时，可以将压缩机的频率调整为原来的1/3，或者更低，本领域技术人员可以在实际应用中灵活地设置微风模式下压缩机的实际运行频率。类似地，在微风模式下，电子膨胀阀的开度可以调整为原来的52/100，或者为其他开度，本领域技术人员可以在实际应用中灵活地设置微风模式下电子膨胀阀的实际开度。并且，在微风模式下，室内机的风机转速优选为在最低档运行。It should be noted that, in the above technical solution, the first preset temperature and the third preset temperature may be set to equal temperature values or unequal temperature values. Those skilled in the art may apply them in actual applications. The relationship between the first preset temperature and the third preset temperature is flexibly set in the medium. In addition, when switching from the cooling / heating mode to the breeze mode, the frequency of the compressor can be adjusted to 1/3 or lower, and those skilled in the art can flexibly set the compressor in the breeze mode in practical applications. The actual operating frequency. Similarly, in the breeze mode, the opening degree of the electronic expansion valve can be adjusted to the original 52/100, or other opening degrees.
